Bad Poo Habit

Tigger has been pooing on my duvet consecutively for the past few days.
I decided, over the weekend, to buy a large piece of plastic sheet to cover the entire bed.
This obviously did not deter him,
as I returned home on Sunday and Monday night to find his poo
on top of the plastic sheet.
So, since yesterday, I brought his food tray and litter box
out of my bedroom and kept my room closed.
I hope this will help rid Tigger of his bad poo habit.
Tigger was still staring from the corner as I left the house this morning.
Just a moment ago, I was updated that he has done his business on the litter tray.
Big sigh of relief!
